Answer:
It will take her nine hours
Step-by-step explanation:
Divide 48 by 6.
8
and divide 72 by 8
The ratio of circumference to diameter is independent of the radius.
Defining C=circumference, r=radius, D=diameter = 2r
Circumference = C = 2 π r = π D
=>
ratio of circumference / diameter
= C/D = π
Answer:
3 times
Step-by-step explanation:
The total number of flips for each round is;
First flip + Second flip + Third flip = 3 flips
Average = [ext]Number of flips/Round[/ext]
Average = 3/1
Average = 3 times.
Check:
Suppose they all match at First and Second rounds,
Average = [ext]3 * 3 / 3[/ext]
Therefore, average = 9/3
Average = 3 times
Answer:
5 months
Step-by-step explanation:
Set up an inequality, using x to represent months.
(The 35 and 40 represent the cost per month, and you add the 100 and 75 just once because it's a one-time fee and not monthly)
35x + 100 < 40x + 75
Now solve for x.
5x > 25
x > 5
This means that the membership will be less expensive after 5 months.
